The customary system of measurment is used in the U.S. The attributes measured by the customary system are weight, length, and capacity. You can convert one unit of measure to another using the equivalencies given in the examples below. Weight The units to measure weight are the ounce, pound, and ton.
16 ounces (oz) = 1 pound (lb)
example: a box of candy weighs a pound
2,000 pounds (lb) = 1 ton (T)
example: a bull weighs about a ton
Length
The units to measure length are, from smallest to largest, the inch, foot, yard, and mile.
example: a quarter is an inch across
12 inches (in) = 1 foot (ft)
example: a ruler is 12 inches or 1 foot long
Plastic Plus Ruler (12")
36 inches (in.) = 3 feet (ft) = 1 yard (yd)
example: doorknobs are a yard from the floor
5,280 feet (ft) = 1,760 yards (yd) =1 mile (mi)
example: 4 times around the A field track is one mile
Capacity The units to measure capacity are the fluid ounces, cup, pint, quart, and gallon.
You can convert one unit of measure to another using the equivalencies below.
8 fluid ounces (fl oz) = 1 cup (c)
example: a cup of coffee is 8 ounces
2 cups (c) = 1 pint (pt)
example: a mug of root beer is a pint
2 pints (pt) = 1 quart (qt)
example: a mason jar holds a quart
4 quarts (qt) = 1 gallon (gal)
example: milk comes in gallon jugs
THE METRIC SYSTEM OF MEASUREMENT
The metric system of measurment is used in the U.S. The attributes measured by the metric system are mass, length, and capacity.
The metric system of measurement is based on 10 and powers of 10. The prefixes used for length, capacity, and mass tell what part of the basic unit is being considered. You can convert one unit of measure to another using the equivalencies given in the examples below.

To change from one unit to another, multiply or divide by a power of 10.
multiply or divide by a power of 10 to change units
Mass
The metric system measures mass instead of weight. Mass is the amount of matter in an object and doesn't change. Weight is the pull of gravity on an object and changes depending how close you are to Earth.
1,000 milligrams (mg) = 1 gram (g)
example: this weight is 1 gram
1,000 grams (g) = 1 kilogram (kg)
example: this tiger cub is 1 kg
1,000 kilograms (kg) = 1 metric ton (t)
example: 1000 water bottles are 1 metric ton
Length
10 millimeters (mm) = 1 centimeter (cm)
example: grid paper squares are one cm
1,000 millimeters (mm) = 10 decimeters (dm) = 1 meter (m)
example: this fish stick is one meter
10 centimeters (cm) = 1 decimeter (dm)
example: the length of a bar of soap = 1 dm
1,000 meters (m) = 1 kilometer (km)
example: 100 school buses end to end = 1 kilometer
Capacity
1,000 milliliters (mL) = 10 deciliters (dL) = 1 liter (L)
example: this water bottle is 1 liter
